This diploma thesis was focused on the analysis of the influence of wood density on the kinetics and quality in the drying process. During the measurement, we focused on a pair of trees, namely maple (Acer campestre L.) and common hornbeam (Carpinus betulus L.). The measurement was performed in two drying modes, at a temperature of 60 ° C and 120 ° C. The aim of the work was to monitor the initial and final humidity, density, humidity gradient, sieving, temperature distribution after the sample cross-section and color change on the samples during the drying process. We described in detail the preparation of samples, the drying regime and the method of obtaining the desired results. At the end of the work, we presented the obtained values through tables and graphs. We summarized the results of the work in the conclusion.
